How to Make Lemoniest Lemon Squares

  1. Preheat oven to 350°F (175°C). Prepare a 9x13 inch baking pan by lining it with parchment paper, leaving an overhang on the sides to lift the bars out later.
  2. Make the crust: In a medium bowl, combine 1 1/2 cups all-purpose flour, 1/2 teaspoon salt, and 1 cup (2 sticks) cold unsalted butter, cut into small pieces. Use a pastry blender or your fingertips to cut the butter into the flour until the mixture resembles coarse crumbs. Stir in 1/4 cup confectioners' sugar. Gradually add 1/4 cup ice water, mixing until the dough just comes together. Press the dough into the prepared pan, forming an even layer.
  3. Bake the crust for 15-20 minutes, or until lightly golden. Let cool completely.
  4. Make the lemon filling: In a medium saucepan, whisk together 1 1/2 cups granulated sugar, 1/4 cup cornstarch, 1/4 teaspoon salt, and 1 cup fresh lemon juice. Whisk in 4 large eggs and 1/4 cup unsalted butter, cut into small pieces. Cook over medium heat, whisking constantly, until the mixture thickens and comes to a simmer. Remove from heat.
  5. Pour the lemon filling over the cooled crust. Spread evenly.
  6. Bake for 25-30 minutes, or until the filling is set and the edges are lightly golden.
  7. Let cool completely on a wire rack. Once cooled, refrigerate for at least 2 hours, or preferably overnight.
  8. Before serving, lift the bars from the pan using the parchment paper overhang. Dust generously with confectioners' sugar and cut into squares.
